  The SAP error message CNV20201123 typically relates to issues encountered during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error message indicates a problem with the mapping of number ranges during the conversion process.
  Cause:
  The error message CNV20201123 suggests that there is a conflict or inconsistency in the number range intervals being used. Specifically, it indicates that the old and new number ranges are not aligned correctly. The placeholders in the message (from-no.=&1, to-no.=&3, etc.) represent the old and new number range values that are causing the issue.

  You can create new number ranges or modify existing ones as necessary.
  
  
  
  Review Migration Settings:
  
  Check the settings in the migration tool you are using. Ensure that the mapping of old to new number ranges is correctly defined.
